Description
Technical field
This utility model relates to thermoelectricity cooling device technical field, especially belongs to a kind of Air-Cooling Island blower fan driving device。
Background technology
Air-Cooling Island is a kind of thermal power plant's cooling technology for the purpose of water saving, it is that the air utilizing nature replaces the industrial heat switching equipment that process fluid is cooled down by water for cooling medium, the consumption of water is only equivalent to the 20%-35% in water-cooled power station, there is the advantages such as cooling water is few, maintenance cost is low, be particularly suitable for the firepower power station in the poor area of water resource。Cooling blower is cooling device important in Air-Cooling Island, existing cooling blower driving device adopts the asynchronous machine drive mechanism with reductor, transmission efficiency is low, it is big to start impact, power consumption is big, reductor adopts more than three grades parallel-axes gears slowing-down structures, input speed is high, the abrasion of reducer gear some mechanical is big, and fault rate, maintenance cost are higher。
Summary of the invention
This utility model seeks to provide a kind of Air-Cooling Island blower fan driving device, to reach to improve the transmission efficiency of Air-Cooling Island blower fan, reduces fault rate, reduces the purpose of maintenance cost。
This utility model Air-Cooling Island blower fan driving device, is characterized by, including permagnetic synchronous motor, the permagnetic synchronous motor special converter being connected with permagnetic synchronous motor one end, and the planetary reducer being connected with permagnetic synchronous motor outfan；The output shaft end processing of described permagnetic synchronous motor has external splines, is connected with the internal spline structure in planetary reducer, and planetary reducer enclosing cover is connected with permagnetic synchronous motor casing。
Described planetary reducer is that one-level arrives two-stage planetary reduction machine, and the output shaft outer surface of this reductor is provided with equally distributed reinforcement and supports。
This utility model Air-Cooling Island blower fan driving device, is driven permagnetic synchronous motor by permagnetic synchronous motor special converter, through the rotating speed that the output of one-level to two-stage planetary reduction machine is required。By permagnetic synchronous motor and reductor integrated design, compact with the asynchronous motor drive mechanism structure compared with reductor, weight saving, save installing space。This utility model starts without impacting, stable, and automaticity is high, and can regulate rotating speed, torque according to heat dissipation capacity demand, improves the transmission efficiency of Air-Cooling Island blower fan, reduces fault rate。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is this utility model permagnetic synchronous motor and reductor assemble cross-section。
Detailed description of the invention
As it is shown in figure 1, this utility model Air-Cooling Island blower fan driving device, including permagnetic synchronous motor 1, the permagnetic synchronous motor special converter 3 being connected with permagnetic synchronous motor 1 one end, and the one-level being connected with permagnetic synchronous motor outfan to two-stage planetary reduction machine 2。As shown in Figure 2, the output shaft end processing of described permagnetic synchronous motor 1 has external splines 6 structure, match with the internal spline structure of planetary reducer 2, it is achieved being transmitted by the power between permagnetic synchronous motor 1 and planetary reducer 2, this connection uniform force can bear bigger load。The rotor 4 of described permagnetic synchronous motor 1 is internal is embedded with high-performance permanent magnet 5, permanent magnet 5 provide rotor field without rotor-exciting。The outer end cap 10 of described planetary reducer 2 is connected with the casing of this permagnetic synchronous motor by bolt, and casing front end 8 and inner end cap 7, the planetary reducer outer end cap 10 of permagnetic synchronous motor collectively constitutes cooling grease chamber, lubricates for planetary reducer gear 9。Described planetary reducer 2 is one-level to two-stage planetary reduction machine, and one-level is to two-stage planetary reduction machine 2 without the part that runs up, and gear wear is little, it is not necessary to frequent more oil change, maintenance cost is low, and low-speed gear transmission efficiency is high。The output shaft outer surface of described planetary reducer 2 is provided with equally distributed reinforcement supporting construction 11, in order to prevent the damage that in fan operation process, planetary reducer 2 is caused by the beat of fan blade。
As shown in Figure 1, this utility model Air-Cooling Island blower fan driving device, permagnetic synchronous motor 1 is driven by permagnetic synchronous motor special converter 3, required rotating speed is exported to two-stage planetary reduction machine 2 through one-level, this utility model is by permagnetic synchronous motor 1 and planetary reducer 2 integrated design, compact conformation, weight saving, save installing space。
